MULTIPLE-GUN-FIRING MPABATUS OR BOMB.

To all whom it may concern. v

Be it known that l, GUNNER A. EKMAN, a citizen of the United States, residing at Winchester, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Multiple-Gun-Firing Apparatus or Bombs, of

I which the following is a specification.

My invention relates to improvements in multiple gun firing apparatus or bombs.

One of the objects of the invention is to provide a gunfiring apparatus or bomb having means for firing simultaneously in all directions a number of shots from a plurality of guns radially disposed therein and adapted, therefore, to combine in one compact structure a maximum firing capacity and to effectively reach a wide radius of territory with concentrated gun fire and with a density of fire proportional to the number of guns employed, while the intensity of fir may be increased in a given area by employing automatic repeating guns.

Another object is to provide a universal firing control adapted to control and operate simultaileously the firing mechanism. of all the guns, thereby centralizing the firing control in one structure.

Another object is to provide means for automatically, safely and. quickly connecting and maintaining constantly in their connected position the firing arms and the universal firing control rings at any angle necessary with relation to. each other.

Another object is to provide safety means for preventing the cartridges or shells in the guns from being fired both while the parts.

are being assembled and until the firing mechanism is actuated at the proper m0- ment.

Another object is to provide safety means for preventing the operation of the universal firing control until the apparatus is ready to be used.

Another object is to provide a simple and efficient firing mechanism, which can be readily and safely adjusted, when the parts of the apparatus are being assembled, and which will easily and effectively codperate with the universal firing control.

It is obvious that the multiple gun firing apparatus or bomb has a wide range of utility in warfare, since it can be used very effectively on airplanes in reaching places with concentrated gun fire that are not possible to reach easily with machine gun fire, while Specification of Letters Patent.

it is equally efiective, when fired from inortars in field operations.

One of the eifectual uses'of the apparatus is, when inflammable bullets are used, in setting fire to buildings, such as aerodromes and inunition plants, since fires may be started in many spots simultaneously. The barrels of the guns may be sighted in all directions or upward so that windows at varying heights may be pierced by inflammable bullets. By this means numerous fires may be started inside of buildings outwardly fireproof, while a number of bombs thus equipped and employed would malre it possible to multiply the number of fires greatly and to completely destroy a large number of buildings.

in order that the nature of my invention may be clearly understood, I have illustrated certain embodiments of the invention in the acc mpanying drawings, in which,-

Figure 1 is a vertical elevation ofa multiple gun firing apparatus embodying my invention in the form of a bomb. Fig. 2 is a central, vertical section on the line 2-2, 1. Fig. 3 is a perspective, partly in section, of the, structural frame showing the universal firing control mechanism and cooperating parts. Fig. 4 is a detail view, partly in section, of the firing mechanism cooperating with one of the guns in its inoperative position and showing the safety means to hold the firing arm out of engagement with the trigger in the inoperative position, also the safety arm below the firing arm to prevent the firing arm from sliding out of position and the consequent pre mature firing of the guns. Fig. 5 is a detail View, partly in section, of the firing mechanism and coiiperating parts in operative position. Fig. 6 is a plan of the firing arm.

Corresponding and like parts are referred to in the following description and indicated in all the figures of the drawings by the same reference characters.

In the drawings 1 designates a multiple gun firing apparatus or bomb, the body of which is preferably conical in form and is composed of a series of side plates 2, each of which adjoins another side plate 2 and e the side plate 2.

forms a portion or section of the circumference of the conical body of the bomb 1. The body of the bomb is formed on a structural frame comprising a circular top plate 3 and a circular bottom plate 4, which serve as the top and bottom of the body of the bomb 1 and are held in. position and relatively to each other by two supporting rods 5, and thus the structural frame being stanchly built gives rigidity tothe bomb. In the top plate 3 and the bottom plate 4 are central openings 6 and 7 respectively, the opening 6 being preferably square for the purpose hereinafter described, in which a slidable rod 8 is adapted to freely slide between the supporting rods 5, while extending radially from the slidable rod 8 are a series of arms 9, to which are attached firing control rihgs 10 of sufficient circumference to encircle clearly the supporting rods 5 and in parallel osition to each other.

The side plates 2, w ich are securely fastened by angle plates 11 to the top plate 3 and the bottom plate 4 and braced withbrace rods "5 extending to therods 5, are provided with a plurality of openings 12, in which are inserted a plurality of barrels 13 of guns 14 in rows, preferably atcertain regular distances from each other, the guns 14 being held securely in position on the inside of the side plate 2 by an annular collar or bushing 15' havin a flange 16 secured to ach of the guns 14 is provided with a'loading chamber 17 and a simple firing mechanism, which may be of any standard type desired, employlng the usual firing pin or bolt and cooking handle 17 a under spring tension, with bolt catch and providedwith a trigger 18 operating the fir ing mechanism, while. a recoil spring 14 may be mounted on cach -brace rod 5, the inner end of which only partially clasps the cooperating rod 5 in order to permit movement of the brace rod 5 on recoil, or other suitable recoil means held'in supports may be attached to each gun 14, if necessary, but it is believed the recoil of any given gun 14 will be equalized by the recoil of a gun on the opposite side of the bomb, hencethe opposing recoil forces would be neutralized.

Below each gun 14 is located the firing mechanism comprising a body portion 19 pivoted at the top 19 to a bracket 20, which is fastened to a side plate 2, the body portion 19 having a slot 21, in which is adapted to freely slide a firing arm 22, which is mount-.

ed in and held in position by slotted guiding lugs 23. The firingarm 22 is provided at its inner end with a slot 22 cotiperating with the slot 21 and at its outer end with a hooked member 24, which cotiperates with a pivoted finger 25 actuated and held normally against a shoulder 26 by a spring 27 but adapted to bend inwardly, when the finger 25 engages the firing control ring 10 10, when the side plate 2 is attached, the

finger 25 yielding as the ring advances and finally snapping back into its initial position and clasping the ring 10 as shown in Fig. 3, and thus the ring 10 is allowed to pass by and thereby the finger 25 coiiperates with the hooked member 24 in automatically clasping the firing control ring 10. In the firing arm'22 is a longitudinal slot 28, in which the trigger 18 of a un. 14 is inserted but out of contact therewith, while springs 29 on each side of the firing arm 22 hold the ends of the slot 28 normally away from the trigger 18 and a safety support or arm 30 extending under the firing arm 22 serves both as a guide for the firing arm 22 and as a safety device to prevent the firing arm 22 from sliding out of position in assemblin the parts while the arm 22 is being attache to the ring 10 and thus the premature discharge ofthe-cartridge in the gun 14 will be averted. Whenthe parts of'the bomb 1 are assembled, each side plate 2 holding a number of guns 14, loaded just before the side plate 2 is placed in its proper position on the structural frame of the bomb 1, is

.employed in a multiple gun firing apparatus apart from a bomb to automatically and simultaneously fire a number of guns.

Below the bottom plate 4 is a weighted conical cap 31 attached to the side plates 2 and provided with an o ning 32 and an enlarged opening 32 ad acent to its base, v

through which the slidable rod 8 passes freely, and adapted because of its form to permit the bomb 1 to cut the air readily in its descent and by its weight to steady and give impetus to the bomb 1. Inserted in a tubular opening in the slidable rod 8 just below the weighted cap 31 and held in a bracket 33 is a safety locking pin 34 having a flat head 36 as shown and having a spiral spring 35 attached thereto and to the bracket 33, adapted normally to be held by the upper edge of itshcad 36 engaging a lug 37 so as to extend through the slidable rod 8 and to securely lock it in a fixed position, while the spring 35 is at'the same time expanded, and adapted to be automatically released by turning the head 36 away from the lug 37 so that the flat side will clear the lug 37 and thereby cause the safety locking pin 34 to be withdrawn by the contraction of the spring 35, by which means the operation of the slidable rod 8 is absolutely controlled and consequently the operation of the firing mechanism cooperating with the slidable rod 8.

In order to relieve and absorb the shock, when the slidable rod 8 strikes the ground, and thereby prevent the breaking or disarrangement of the firing control rings 10, firing arms 22 or other parts of the firing mechanism, expanded shock absorbing spiral springs 38 and 39 are mounted on the slidable rod 8, one spiral spring 38 extending from the top plate 3 to a flange 40 on the slidable rod 8 and the other spiral spring 39 extending from a flange 41 near the end of the slidable rod 8 to a flange 42 above it, adapted to freely enter the opening 32 when the slidable rod 8 is pushed upward, the flange 42 also serving to hold the spiral spring 39 out of engagement with the safety locking pin 34. When the pin 34 has been withdrawn, the spring 39 engages the base of the conical cap 31 and cooperates with the spring 38, in holding the body of the structure yieldingly between them and acting as cushions in absorbing the shock at the moment of impact.

The upper end of the slidable rod 8 is provided with radial planes 43 to direct the bomb in its flight, the radial planes being held stationary by suitable means, as a square key 8 fastened securely to the slidable rod 8 and adapted to cooperate with and slide in the square opening 6 in the top plate 3 and having guiding flanges 6 on the top plate 3. On the lower end of the slidable rod 8,which extends sufficiently below the body of the bomb 1 to permit the bomb to be fired high enough above the ground to make the fire of its guns 14 effective, is an impact member 44 adapted to engage the ground or other hard surface which the bomb may strike, while the flange 41 stops the slidable rod 8 from going too far into the ground.

In operation the multiple gun firing apparatus or bomb, when used on an airplane, as shown in Figs. 1 and 2, is held by a suitable hanger having spring holders or arms, from which it may be released readily and instantly by the airman from any desired height, after the safety locking pin 34 has been released either by hand or some suitable mechanical device. In traveling through the air the weighted conical cap 31 allows the bomb to overcome the resistance of the air, as well as giving stability and impetus to the bomb, while the planes 43 direct and keep the bomb true in its flight. The instant the impact member 44 strikes the ground or other surface the body of the bomb 1 is caused to slide downward a limited distance on the slidable rod 8 by the weight of the conical cap 31, having therearms 22 and causing the lower end of the slot 28 in each firing arm 22 to engage and press the trigger 18, whereupon all the guns 14 are simultaneously discharged. The force of the recoil of all the guns 14 being equally distributed the bomb 1 will remain in its proper upright position, as in falling, during the snnultaneous discharge of the us 14, since theyare distributed all aroun the I conical shaped bomb 1 in rows at equal distances from each other and are sighted or directed at many points in all directions, but preferably are placed horizontally above each other at varying heights from the ground, for example from one to six feet, and when desired for some special purpose, as when using cartridges with inflammable bullets, as previously described, the guns may be sighted or directed at any angle desired. Thus the guns 14 may be placed in oblique and staggered rows, thereby covering a wide range.

ince the bomb is designed preferably to be employed only once or for a single discharge, the guns 14 are very light in weight and, are adapted to fire bullets approximately 300 yards or varying distances if desired, and a bomb approximately six feetlong and three feet in diameter would carry a number of hundred of guns sighted or directed so as to be equally divided in covering a given circular area.

Therefore, the efliciency of the' bomb is clearly apparent, when it is considered that, assuming that its guns 14 would fire bullets approximately 300 yards, the radius of ground within the range of fire in all directions would include a circular area of a number of thousand of square yards, while the number of bullets to reach any area within range of the bomb will be proportionately increased as the area decreases toward the bomb or it varies directly with the radial distance from the bomb, until the maximum density of fire is reached adjacent to the point Where the bomb strikes.

Many variations are possible in the number of guns used, as well as in the firing mechanism, while ifso desired, the slidable rod 8 may be provided with a device adapted to operate a detonator-to fire an explosive charge within the bomb after the guns 14 have all been discharged thus destroying the bomb and preventing it from being used by the enemy.

While the multiple gun firing apparatus or bomb is adapted particularly for use as an-aerial bomb, it may be thrown from mortars and used effectively in land operations,

- the simultaneous actuatin ple gun firing apparatus or bomb are simple in construction, and adapted to be readily assembled, while many of the parts, especially the parts of the firing mechanism, may be readily'stamped from metal.
